Good news! Released from PT after 18 visits, now I'm on my own. I began going to water exercise about month ago, twice a week. Best of all, I rode my bike for the first time last week, and had my third ride today. So, it's only 1.3 miles from my house to my job, but it's a gentle incline the entire way, and I've got a hella heavy bike. I can tell a slight improvement in my strength already.
Unfortunately, I appear to have either biceps tendinitis (out of nowhere, not even my cane arm) or a bone spur on my rotator cuff. The same day I was released from hip PT, I started shoulder PT!!
